OBJECTIVE No data exist on the functional relevance of collateral vessels in patients undergoing percutaneous coronary intervention (PCI). Also, the subtle effects of improved collateral flow on right ventricular (RV) function are difficult to assess. However, novel echocardiographic approaches like tissue-Doppler imaging (TDI) and two-dimensional(More)
OBJECTIVE Despite many potential benefits, thiazolidinedione (TZD) use has been associated with increased exacerbation rate of heart failure due to fluid retention. In our study, the effect of rosiglitazone and pioglitazone on myocardial function in patients with type 2 diabetes mellitus (DM) and normal left ventricular systolic function was evaluated by(More)
Percutaneous closure of secundum atrial septal defects (ASD) may be complicated by immediate embolization. We report on a 35-year-old woman who underwent percutaneous device closure for a secundum ASD. The diameter of the defect was measured as 4 mm by two-dimensional transesophageal echocardiography and a 7-mm Figulla ASD occluder device was implanted(More)
BACKGROUND Fractional flow reserve (FFR) has become an established tool for guiding treatment, but its graded relationship to clinical outcomes as modulated by medical therapy versus revascularization remains unclear. OBJECTIVES The study hypothesized that FFR displays a continuous relationship between its numeric value and prognosis, such that lower FFR(More)
OBJECTIVES We aimed to investigate the relationship between the platelet-lymphocyte ratio (PLR) and coronary collateral circulation (CCC) in patients with stable angina pectoris (SAP) and chronic total occlusion (CTO). METHODS A total of 294 patients with both SAP and CTO were classified according to their Rentrop collateral grades as either poor (Rentrop(More)
We evaluated whether the neutrophil-lymphocyte ratio (NLR) was associated with the presence, severity, and extent of coronary atherosclerotic plaques detected by computed tomography angiography (CTA). We studied 238 patients who underwent dual-source 64-slice CTA for the assessment of coronary artery disease. Coronary arteries were evaluated on 16-segment(More)
OBJECTIVES Although atrial fibrillation (AF) is one of the most common rhythm disorders observed in clinical practice, a multicenter epidemiological study has not been conducted in our country. This study aimed to assess our clinical approach to AF based upon the records of the first multicenter prospective Atrial Fibrillation in Turkey: Epidemiologic(More)
AIM Nondippers are known to carry a high risk of cardiovascular morbidity and mortality. The aim of this study was to investigate the effects of dipper and nondipper status of hypertension on longitudinal systolic and diastolic functions of left atrial (LA) myocardial tissue by means of two-dimensional speckle-tracking echocardiography in treated(More)
BACKGROUND Pseudoexfoliation syndrome (PEX) is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular(More)
